Researchers in Canada have found that nearly zero-energy buildings (NZEBs) with on-site solar energy generation should not exceed an energy use intensity (EUI) of 50 kWh/m2a, which they said corresponds to a maximum of 10 floors. They also ascertained that the maximum permitted EUI by net-zero energy status is 17–28 kWh/m2a.

One of Australia’s major winemakers has taken a big step forward in its transition to 100% renewable energy, switching on what it claims is the largest winery solar installation in the country. The 2.6 MW rooftop and carport array is the continuation of a wider trend of winemakers adopting solar to bring down energy costs and strengthen their brands.

Australian battery technology company Vaulta has unveiled its first dedicated residential battery with the small-scale energy storage system purportedly able to operate for 4,000 cycles with an 80% depth of discharge.

Renewable energy developer Neoen will scale up the installed capacity of the Western Downs Battery being built in Queensland to 270 MW/540 MWh as it looks to keep pace with rising demand for energy storage and realise opportunities across Australia’s evolving energy system.

Australian natural hydrogen explorer Gold Hydrogen plans to start drilling on South Australia’s Yorke Peninsula later this year after early testing at its maiden Ramsay project site detected the presence of naturally occurring hydrogen in soil samples.

The SeaVolt consortium says it will launch an offshore floating PV demonstrator off the Belgian port of Ostend. The main companies – Tractebel, DEME, Equans and Jan De Nul – say the anchored floating array will collect data for at least a year to scale up the tech.

Addressing climate change means enduring some economic pain in the early part of this century to avoid worse outcomes in the long run. But recently the narrative has shifted from pain to opportunity.

A grid-connected community battery has gone live in Sydney’s western suburbs with New South Wales electricity distributor Endeavour Energy trialling the technology as a means to maximise the benefits of rooftop solar generation and more efficiently manage supply and demand in the network.

Scientists in China have proposed to use an algorithm that simulates the behaviour of foraging bees to shape a new grid-forming inverter design. The approach is designed for both grid-connected and islanded inverters.

Installation robots are moving from test centres to the field. American technology companies Sarcos Technology and Robotics Corporation and Terabase Energy recently announced key business developments.
